Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522896, here are decompositions:

  • 7 + 31522889 = 31522896
  • 23 + 31522873 = 31522896
  • 73 + 31522823 = 31522896
  • 149 + 31522747 = 31522896
  • 179 + 31522717 = 31522896
  • 227 + 31522669 = 31522896
  • 233 + 31522663 = 31522896
  • 239 + 31522657 = 31522896

Showing the first eight; more decompositions exist.
